I found out that my compression on my lt1 383 is going to be around 11:8:1..Is anyone running around the same compression?If so,did you have any issues running on pump gas?The highest octane I found around me is 94...I do have access to 115 race fuel.

 

I know lots of people that run pump gas on 12:5 compression. The reverse flow cooling really helps us with that.

 

As long as you have GOOD tuning and your cooling system is in great working order you won't have a problem. I run 12.5+ compression with my motor on 93 octane daily.
